Polyacrylamide (PAM) is a linear organic polymer, and it is the most widely used flocculant in water treatment chemicals. It can enhance flocculation, reduce the cost of clean water, improve water quality, and remove organic matter and algae in the water.
Types of Polyacrylamide (PAM)
There are three types of polyacrylamide, they are Anionic Polyacrylamide(APAM), Cationic Polyacrylamide(CPAM) and Nonionic Polyacrylamide(NPAM). They can be used as effective flocculants, thickeners, paper intensifiers and liquid drag reducer. Please feel free to contact us to find out which kind of PAM is best for your business.
APAM is white powder. Its water solubility is good, can dissolve in any proportion of water and insoluble in organic solvents. Mainly used for flocculation and sedimentation treatment of various industrial wastewater, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and other sewage treatment. It can also be used to clarify and purify drinking water.
Application of APAM:
1.Polyacrylamide water treatment. It has the best effect on the treatment of neutral or alkaline sewage with thick suspended particles, high concentration, cations with positive charges, and with a PH value of 7-14. Such as iron and steel wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and other sewage.
2.PAM water treatment. Many sources of domestic water come from rivers and lakes, with high sediment and mineral content. Although it is filtered by precipitation, it is still not up to standard. At this point, flocculant should be added. Using anionic polyacrylamide as a flocculant, the dosage is 2%-5% of the non-polar flocculant, but the effect is dozens of times that of inorganic solvent.

CPAM is a linear polymer compound. Because it has a variety of active groups, it can adsorb hydrogen bonds with many substances and has the functions of removing turbidity, decoloring, adsorption, adhesion and so on. It is suitable for wastewater treatment in dyeing, paper making, food, construction, metallurgy, mineral processing, oil field, aquatic product processing, and fermentation, etc. Especially suitable for the dewatering treatment of municipal sewage, municipal sludge, papermaking sludge.
1. As a flocculant, Cationic Polyacrylamide is mainly used in industrial solid-liquid separation processes, including sedimentation, clarification, concentration, and sludge dewatering processes. It is commonly used in industrial wastewater, urban sewage, food processing wastewater treatment. Through its excellent bridging condensation function, the colloidal particles are aggregated into large flocculent and then separated from the suspension. The effect is obvious, adding less.
2.Cationic Polyacrylamide can be used as a dry strength agent, retention agent and filter agent in the paper industry. It can greatly improve the quality of paper, save costs, improve the production capacity of paper mills. It can be direct with inorganic salt ions, fibers, and other organic polymers electrostatic bridge effect to enhance the physical strength of paper, reduce the loss of fibers, accelerate the role of water filtration. It can also be used for white water treatment. At the same time, it can have an obvious flocculation effect in the deinking process.
Non-ionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can accelerate the settlement of particles in the suspension. It has a very obvious effect of speeding up solution clarification and promoting filtration. It is highly water-soluble and can be completely dissolved in cold water. Adding a small amount of non - ionic polyacrylamide can obtain a great flocculation effect.
1.Widely used in the treatment of chemical industrial wastewater and waste liquid, and municipal sewage treatment. Especially when the sewage is acidic, this product is the best choice. It can be used with inorganic flocculant.
2.In the petroleum industry, it has been widely used in the fields of oil recovery, drilling mud, waste mud treatment, water channeling prevention, reducing frictional resistance, enhancing oil recovery, eor, etc.
3.In the textile industry, it is used for textile sizing agents, which can make the properties of the slurry stable, less pulp falling, low breakage rate of the fabric, and smooth cloth surface.
4.Used in the paper industry. First, the retention of fillers and pigments can be improved to reduce the loss of raw materials and environmental pollution; Second, it can improve the strength of the paper (including dry strength and wet strength). In addition, the use of Nonionic Polyacrylamide can also improve paper tearing and porosity to improve visual and printing performance, and can also be used in food and tea wrapping paper.
5.Other industries: it can be used in the production of sugarcane sugar and beet sugar in the food industry. It also can be used in synthetic resin coating, building materials industry, electroplating industry, printing, and dyeing industry.
